Methadone detoxification is a process which must be supervised by substance abuse professionals within a drug rehab program who realize how difficult and challenging methadone detox can be. Methadone detoxification is known to be far more serious in terms of symptoms and duration than even heroin detox, and individuals often revert back to methadone to alleviate withdrawal symptoms or, worse yet, turn to heroin or prescription opioids to ease symptoms. This is why methadone detoxification should only be done under close supervision at a drug rehab facility which has practical experience in handling this type of detox, and where the person can receive further treatment services to handle all addiction issues.
